11 09? PEPNG BUCKLE ap u up r l d i ust 1.0, 1932. s ri in ezs ea This invention relates to improvements vin p P Q g buckles. ,1 t. a

Loop prong,buckles,previous to the improvement about to be disclosedphave' been made and used in a manner common to all as regards the loop portion of such buckles, the loop portionbeing formed to provide abut ton-receiving loop, of suflicient interior-dimensions to permit a button to be passed therethrough, and a button-retaining loop for the repose .of the metal shank of an in-,

serted button, these loops being defined by means of an intermediate contracted throat portion of sufiicient Width to admit button shanks of extreme diameter in passing from one loop to the other. The ease'withiwhich button shanks are able to leave the buttonretaining loop of this type of loop prong buckle renders the button'capable ofunintentional release from the device when the strap therebyheld is not taut. The improved 10 p" P ng bu kle. gi s u i y o h rete t n iii n i r d butt and f lse e m na he larger of the usual associated loopsand' the contracted throat portion of the ordlnary o culiar to other features including the cooperation of a folded strap portion to'secure a seated button. 1

The object of the present improvement is to provide a prong buckle with a button-retaining loop portion so associated with a portion of a strap, an end of which is threaded into and held within the prong buckle, that the strap is adapted to cooperate with the retaining loop in preventing an unintentional this and other objects as may hereinafter appear the invention isslibject to suchmod ifications as may come within the'scope'of what is hereinafter claimed; 7 i

The character of the improvement may be best understood by reference toone illustrative device embodying the invention and illustrated by theaccompanyingidrawing in which theFigure; an upright frontele'va i 2 tion' of'the device having a seated button, a part obscured by, the'bu-t'ton'being illustrated by dotted lines ;'the' Figure 2'isa. similar ele-V vation of the device, but illustrating a buti a lifted from its s e p i n; t e 7 ure 3 an upright front elevation of the ole Vice as illustrated by the first figure, buthaving a strap end threaded into and heldfthere in; the Figure 4 isan upright front elevation of the device as illustrated by the second figure, but having a strap end threaded into and held therein the Figure Boris a cross-section on the line 5+5 of the third figure, but illlus- I trating the button attached to a member thereby supported; the Figure G is acro section on theline '6'-6 of[the'fourth fi ure,

Referring more particularly to the draw? ing the device, as illustrated, comprises the buckle frame 1, thepronged member 2 hav-' ing th prongs 3 and. 4, and t e spa ed .p-ivot l conne t n v5 and 6 co mon ox uch uckles th s r ctur t ereby c d n h r lat ely mo ble buckle 1 010 7 a 0- 7 gether providing the ydevicei with the upper he 9 and the low a he b nete mfh e is 'fhrme i ,thl e r; 0, the ba e if the r taini g 9 91 PriQ i his th ea .12 f he me al h n 1 1 fv a i bee 1.4;; the utto 1 r p ins the shi 12; being illustrated by theFigures 1, '3 and 5. For the purpose of describing certain positions of the button 14 it is illustrated withadotted horizontal diameter 20 and adotted vertical diameter 21. *VVhen the shank 13 0f a button 14: is seated within the retain: ing loop 11, as illustratedby-the Figure 1,

inboth instal ices thedottedvertical diameter 21 is intersected by the dotted straight" line 22 connecting the lowest portions of said spaced pivotal connectionsf) and 6. A strap 30 isgthreadefd intothe device by inserting the' end31of the strap 30 into the buckle loop 7 from the rear of the device,

the prongs 3 and 4 being urged through the strap material as a positive holdingmeans. The end 31 of the strap 30' is then inserted into the-buckle loop 8 -from the'front and pulled taut. In thus threading the strap; .0 into the device, that portionx32 of the strap 30, lying over the spaced pivotal connec tions 5 and 6 and from thence dipping into thebuckle loop 8, extends along the stralght and 6, amiddle portion 33 o-fthe strap 30 tural part. f

alongsaid dotted line 22- remains flexible, it having no immediate support from a struc In use, therefore, while, with amp threaded into the device, there is ample space to insert a button 14 into the retaining loop '11 by way of the open space 23 yet, when the a strapis threaded into the device as aforesaid thebutton 14 may be inserted and re- 'leasedqonly by the'flexible yielding-ofthe strap-portion To insert the button 14 111-" I to the' retainingloop 11, the button 14 1s,

. tippedso that the irear surface -15 ofthe low- .er portion of the button 14 may engage the outer surface of the upper'portion of the retaining; loop 11, then by using thattengage. ment as a fulcrum the top portion of thebutton may be urged pastthe yielding-flexible portion-33 of the strap .30 and thus permit the button 14 to slide into the retaining loop 11 and the shank .13 to be seated uponthe seat 12, as illustrated by the Figures 1, 3 and '5. While thusinserted into the retaining sociated buckle loops, the pronged member having a button loop portion providing a seat for the shank of a button, the said por tion being so formed that a button is irisert able within and releasable from-said button loop portion only through said lower buckle loop, and a strap threaded from the rear "into said upper buckle loop and back into the lower buckle loop and thusmaintaining a flexible strap portion extending across said space along a line intersecting the diameter of a button enteringor leaving thebuttonv 0p, rt ea v z 2. A loop prong buckle comprising a buckle frame loop and a pronged member loop hav ing spaced pivotal-connections, one with the other, proyiding a space between the pronged ends of the prongedmember, the frameand the member, providing upper and lower buckle loops, the lower buckleloophaving a button-retaining. loop portion providing a seat for the shank of a button,'and a strap, threaded from the rear into the frame loop and then back into the pronged member loop and thus providinga flexible strap portion extending across said space and lying in a substantially vertical plane parallel to and at the rear of the plane ofa seated button, sald strap cooperating with the retaining loop. to. secure said button against unintens tional release, but flexibly yielding to permit said button.

loop 11, the button 14 is therein secured against unintentional release by reason of the fact that any casual movement of the button 14 within the retainingloop 11 is met by the strap portion33 intersecting the vertical diameter 21 behind the button 14, that position of; an unseated button 14 being illustrated by the Figures 2, 4, and 6. To release the the button 14 is raised and inclined backwardly so that its horizontal diameter 20 is thereby raised above the. lower bar 10, the top. of the button14 engaging and displacing the flexible portion 33 ofthe strap 30' thus yielding, as illustrated by the Figure 7,to permit, the release of the button. 14; from Within the retaining loop 11. r H V p I f I button 14 from within the retaining loop. 11, 7 I
